LEA — Beta vulgaris subsp. vulgaris

Summary

BvLEA (BVRB_9G217050) on sugar beet chromosome 9 encodes a dehydrin family protein with a conserved dehydrin signature and lipid-binding properties, including phosphatidylglycerol, phosphatidylserine, phosphatidate and phosphoinositide binding, as well as metal binding. The gene is associated with responses to cold, abscisic acid, oxidative stress, drought, and dehydration, and is linked to cold and freezing stress tolerance, osmotic and salt stress tolerance, membrane stability, and seedling establishment. It is associated with ABA signaling, embryogenesis, anthocyanin metabolism, DNA replication, and defence against fungi. The protein localises to the vesicle membrane, membrane, cytosol, cytoplasm, and nucleus. Studies of related genes in other species link the family to ABA sensitivity, hydrogen peroxide accumulation, drought stress resistance, drought tolerance, salt tolerance, and osmotic stress response.
